Feature

• 1. 15-2000 μh detection Range
  • The loop detector supports a wide detection range from 15 µH to 2000 µH, accommodating various loop sizes and configurations for versatile application in different traffic detection scenarios.
  • The wide detection range enables our loop detector to detect all kinds of vehicles, motorcycles, cars, Ultra long truck, buses and so on

• 2. Compact Side
  • The compact and well-engineered housing combines all industry requirements for features and functionality, allowing this detector to be incorporated into any existing traffic detection system.

• 3. Diagnostic Capabilities & LED Indication
  • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through the LED state, ensuring optimal performance and reducing downtime.

• 4. Selectable Presence Time
  • The output of the presence relay can be selected to limit a detect output to a fixed time (greater than 30 minutes) while a vehicle remains on the loop, providing flexibility in traffic management.

• 5. Automatic Sensitivity Boost (ASB)
  • This feature reliably detects large truck-trailer combinations and high-bed vehicles by automatically boosting the sensitivity to maximum upon vehicle detection, ensuring accurate identification.

• 6. Automatic Environment Drifting Compensation
  • Loop detectors (or other sensors) automatically adjust and calibrate themselves to changes in environmental conditions, maintaining detection accuracy and stability despite varying weather and environmental factors.

• 7. 17 Dip Switch Setting
  • The dip swich design on the shell makes the setting of loop detector easier and clearer, which is very user-friendly for users. Users can set all the functions first and then install the loop detector.

• 8. Dual Channels work Cooperatively or Independently
  • Dual channel loop detector can be used as two single channel versions, Supports two independent detection channels.
  • Also allowing for the simultaneous monitoring of multiple loops, loop detector has the ability to recognize direction in single-channel applications. enhancing the flexibility and accuracy of vehicle detection.

• 9. Anti-crosstalk interference.
  • Through the dip Switch, the frequency of the loop detector can be adjusted to prevent crosstalk interference caused by the installation of two loop coils too close.
